Fig. 3. Changes in VAS (A), ODI (B), and RMDQ (C) of the real rPMS group and sham rPMS group according to passage of time. Differences in changes of the VAS, ODI, and RMDQ over the course of time between the two groups were significant (p=0.003, p<0.001, and p=0.006, respectively). In comparing the two groups, there was a significant difference in VAS at session 5, but not at session 10; ODI showed a significant difference at sessions 5 and 10; and there was a significant difference in RMDQ at session 5 but not at session 10. VAS, visual analogue scale; ODI, Korean version of Oswestry Disability Index; RMDQ, Korean version of Roland-Morris Disability Questionnaire; rPMS, repetitive peripheral magnetic stimulation. ^*p<0.05, ^**p<0.01, ^***p<0.001.
